SPECIFICATION forming part of Letters Patent No. 518,666, dated April 24, 1894. Application filedApril 4, 1893- Serial No. 469,000- (No model.)

To all whom it may concern:

Be it known that I, JOHN F. DORNFELD, of

Watertown, in the county of Jefferson and State of Wisconsin, have invented a new and useful Improvement in Malting-Floors, of which the following is a description, reference being had to the accompanying drawings, whlchare a part of this specification. My lnvention has relation to improvements in malting floors, and it consists in the improved construction hereinafter more fully set forth.

The principal objections to the ordinary perforated mal'ting floors now in use are, first, the difiiculty experienced in cleaning the same, and as cleanliness is an important desideratum in themanufacture of good malt, 1t is obvious that this object cannot be obtained where thousands of small holes are required to be looked after, which are practically inaccessible for cleaning purposes; second, the other equally great objection in all floors thus far built is that it requires too much manual labor to remove them from their plan E floor position to a position suitable for cleaning; and third, that all floors thus far built are so heavy as to create an additional Weight on the building walls, thus rendering them not adaptable to structures built for use under the old systems wherein inadequate provision was made for supporting floorings possessing the maximum weight.

The primary obj ect, therefore, of my invention is to provide a perforated malting floor of such construction that it can be readily rolled up when it requires cleaning, and during the operation of rolling effectually and rapidly cleansed. The floor furthermore is not only durable in construction, but at the same time inexpensive of production, the cost being reduced to the minimum, and light in weight so as to adapt it to buildings already constructed, having no provision for supporting heavy floorings.

In the accompanying drawings, Figure 1 is a vertical sectional view of one end of a fragment of a malting room, showing my improved flooring properly in place therein. Fig. 2, is

a similar view of the opposite end of the room,

floor. Fig. 5, is a transverse section of Fig. 4 taken on a line through the indentations of the caps, and Figs. 6, 7 and 8 are perspective views of fragments of modified forms.

Like numeralsof reference denote like parts throiighout the several views.

Referring to the drawings, the numeral 1 indicates the floor of a malting room, and 2 a fragment of the wall of a vertical attemperator flue, located medially at one end of the malting room. A box or chamber 3 is formed into the attemperator fine, and made the duct for the passage of air from the same, to and through an aperture 4 into the air chamber beneath the malting floor, hereinafter more fully described. This chamber 3 is provided with a cold water pipe 5 extending through it horizontally, which pipe is provided with a series of apertures or spraying nozzles 6, so that water in the pipe under pressure will be discharged in a spray into the chamber 3 where it mingles with the air and cools it to such an extent as is desired. It is sometimes desirable to hermetically close this passage for air through the chamber 3, and for that purpose I provide a cover-7 having a downwardly. extending flange 8 adapted to fit in a channel or groove 9 above the top of the aperture in the box. This groove is adapted to contain water, and the cover 7 is let down by means of a pulley and cord arrangement 10, and the flange 8 being inserted in the water, a hermetically sealed joint is formed.

The malting floor is shown clearly in detail Fig. 4, and when in proper position with in the malting room is supported on posts 11,

at a distance above the floor 1, whereby an air chamber is formed between the two floors.

Vertical walls 12 extend up from the malting room floor 1, and form side walls for the malting floor, thereby preventingthe escape of grain or malt from the same.

In practice it isimpossible to construct the malting floor of sufficient width to cover the width of the average malting room, and I therefore provide a floor composed of a series of longitudinal lengths, each length in turn made up of sections, as clearly shown in Fig. 3. In this figure one of the lengths of the floor is shown as supported at one edge upon the flange of a cap 13 fitting over the top of the supporting post 11, and the other edge supported upon an L-shaped bracket 14 let into one of the vertical side walls .12. The next length of the floor, of which a fragment only is shown in Fig. 3, is supported at one edge upon the other flange of the cap 13, and its opposite edge may be supported either upon the flange of a cap fitting over another post as 11, if the width of the room permits it, or may he supportedon: an L-shaped bracket 14, let into the opposite wall, not,

shown, of the room. p p

In the principal form of the floor illustrated in Fig. 4, the same is shown as consisting of a series of inverted U-shaped. sections 15, having a series of elongated openings 16 upon their upper sides. The several sections of the floor are arranged adjacent, so that the depending flanges or legsl7- thereof will contact.

After'adjusting these clamps to place, indentations 19 are made in one side of each clamp,

. which form the registering bulges clearly shown in the sectional view Fig. 5, and prevent the clamps from working out of place. The depending flanges or legs strengthening each longitudinal lengththroughout,and at the same time preventing sagging of each longitudinal length. The oppositesides of each clamp, are provided, near opposite ends, with recesses 20, 20. Longitudinal reinforcing ribs 21, 21 are arranged beneath the upper sides of the sections, at opposite ends, and

.the extremities of these ribs rest in the recesses 20. These ribs are preferably com-.

posed of a solid piece of half round iron.

In the modified form shown in Fig. 6 Ishow the several sections composed of T-iron and fastened together by Ineansof longitudinally arranged bolts 22, said bolts'connecting the flanges of contiguous sections at QPPOSite ends. It will be noticed that in this form no perforations are providedbut sufflcientspace is afiorded between the'edges of the heads of the T-iron to permit the free passage of the air.

In Fig. 7 each section of the floor is of L- form, the upper sides of the heads being perforated as in Fig. 4. Thebolts 22 connect theseveral sections in the same manner as in Fig. 6, at the same'timeleaving a space between the edges of the upper sides of the con-- tiguous sections, whereby the air is permitted not only to flow through the openings, but also through the spaces. I

Fig. 8 is the same form as. illustrated in Fig. 4, excepting that the several sections are arranged with a slight intervening space and the depending flanges are connected by the bolts 22 instead of clamps. ln this form also the air passes through the 'ope'nings and the intervening space.

It'will be seen from inspection of, Figs. 4, 5, 6, 7 and 8 that each length of the malting floor' is composed of a series of adjacent sec- In order to secure these flanges together, I provide clarnps 18' which secure the flanges in the manner "clearly shown.

stitute, whereby the narrow portionsof the sections are disposed longitudinally.

In Fig. 2 of the drawings, which represents the end of the malting I'OOlIl opposite to that shown in Fig. 1, is illustrated a winding drum .2 l,'upon which may be wound a length of the flooringof thenlalting room. Byarranging and uniting the sections in the manner above explained, the length of floor may be wound longitudinally on the drum 24, inasmuch as the jointed narrow portions of the sections will readily permit of bending in conformity with the circular contour of the drum;

When it is desired to clean the malting floor, the end of a length'thereof asshownin Fig. 2, is connectedtbthedrum in any desired inannenand the latterrolled toward the end of (the malting room shown in Fig.1, which of course, has the effect of winding the r As it is thus wound, it can flooring thereon. I bemostjconveniently, expeditiously and there oughly ,cleaned as is obvious.

18 will come to rest on the top surface of the floor, and when the drum has reachedthe back end of the malting compartment shown in Fig. 1 the entire weight of the malting floor will have to be supported by said flanges and caps resting on the top of the floor. The effect of the pressureof these flanges and clamping caps would ordinarily be to bend the flooring down. It is for this reason that I provide the reinforcing ribs 21 which serve to take thepressure of the flanges and caps,

as will'be readily understoodby reference to Figs. 2 and 4t. As the floor is rolled up, the 2 distance between the flanges is increased but slightly, notenough to'affect the bearings for p i the reinforcing ribs, or to permit of their dropping from these hearings or notches. In providing a loose drum adapted to wind up. the floor from the front toward the back end of the malting room, said floor is thus wound up without being dragged upon its support-s. It is advisable to provide as many drums as there are sections in one compart .mentor floor.

. What I claim as my invention, and desire to secure byLetters Patent, is r 1. The combination, ofa malting room, supports, and a malting fioor'resting upon the supports, comprisinga series of longitudinal lengths, each length in turn comprising a se- J .ries of flexibly united sections forming a floorin g of separate windable lengths, said sections having suitable spaces or openings for I the pas'sageof air, and one end of each length of the floor resting looselyupon or detachi ably connected tothe supports to permit of its. attachment to a winding drum, wherebyj the separate lengths of the floor maybe cleaned, as the drum is rolled from one'qend tions, arranged lengthwise transverselyof the longitudinal length which. they unitedly con I In rollingu'p alength of thefloor uponthe loose roller, the I dependingflangesli, and the clamping caps C of the room to the other, and the lengths separately convolved or wound" thereon, substantially as set forth.
